How to tell if the valve oil seal is leaking oil

2022-10-31

 1. The most common oil leakage is the problem of valve oil seal and piston ring. How to judge whether it is a piston ring problem or a valve oil seal problem can be judged by the following two simple methods:

1. Measuring cylinder pressure
If it is the piston ring that determines the amount of wear through the cylinder pressure data, if it is not serious, or through additives, it should be repaired automatically after 1500 kilometers.

2. Look for blue smoke in the exhaust vents
Blue smoke is a phenomenon of burning oil, mainly caused by pistons, piston rings, cylinder liners, valve oil seals, and wear. Can cause oil burning. In order to judge whether the valve oil seal leaks oil, it can be judged by the throttle and the throttle release. The exhaust port of the gas valve is due to excessive wear of the piston, piston ring and cylinder liner; the blue smoke phenomenon is mainly caused by damage to the valve oil seal and wear of the valve guide. caused.

2. Consequences of valve oil seal leakage
The valve oil seal oil will burn in the combustion chamber. If the valve oil seal is not tightly infiltrated into the oil, the exhaust gas will show blue smoke. If it is easy to generate carbon deposits for a long time, there will be a valve that is not tightly closed. Insufficient combustion. It can also lead to the accumulation of carbon in the combustion chamber and nozzles or the blockage of the three-way catalytic converter; it can also cause a decrease in engine power and a significant increase in fuel consumption, and damage to related equipment, especially the working conditions of the spark plugs are significantly reduced. It can be seen that the consequences are still very serious, so you should replace the new valve oil seal as soon as possible.
